Hi Alberto;
Very interesting, thanks for sharing.
What did you use as a light source for the collimation testing on the horizontal at 70 meters?
And aren't you afraid that the collimation will need to be re-done when you move the scope into a more normal near vertical orientation?
Or are you just interested in the optical properties of the C11 for the horizontal testing?
Also, in the zip focal test folder is the image "100116-Ir-ScarceSeeing-NotFullyCollimated.jpg". That looks like a nice IR Mars shot.
TTYL..

Thank you to all.
I installed the Moon Atlas on my iMac and it works fine.
I'm wondering if while installing on my MacBook i had the bad idea to change the path for the installation.
I often use a different folder for my applications in order to keep them separated from the Apple applications.
When i did so, i noticed a weird behaviour : the installer created a new "applications" folder inside my folder and i considered that a strange behaviour.
On the contrary while i installed on the iMac i left the default Applications folder and it worked fine.
Of course now i must do the same thing on the MacBook in order to confim such theory.
A quick test consisting in moving the Atlas folder to the Applications folder didn't work.
I'll try unistalling it and reinstalling in the default folder.
About the C11: it seems very good.
I did a intense set of collimation and testing on ground objects (the seeing was very bad) and i got a nice collimation at f. 46.6 (more than 13 meter focal length). It is the first time i get a very nice airy circle using an artificial star far approx 70 meters from my scope.
This is the resume of such collimation and testing:

i did a rough Ronchi test and it seems nice too:

If someone is interested about the C11 test at f.46.6, f.21.6, f.10, f.7.83, f.3.97, f.2,88 this is the set of images of a building placed exactly at 1500 meters far from my house.
The pixels measurements have been done in order to calculate the resulting focals assuming that the "normal" C11 is 2800 mm.

I have everything downloaded now, all the options. Played with it a bit, but havent had a lot of time to spend on it today.
